Factors that affect decking prices

Many different factors will influence the total decking price per m2, from decking installation to the materials you choose, and more. Here are a list of factors to consider when budgeting for your new deck build:

1. Materials

The type of materials used for the deck plays a significant role in determining its cost. For example, pressure-treated wood tends to be less expensive than hardwoods like Ironbark or Merbau. Composite decking materials are generally more expensive than wood but can have lower maintenance costs over time.

2. Size and Layout

The size and layout of the deck will directly impact the amount of materials needed. A larger deck will require more materials and labour, which will increase the overall cost.

3. Labour Costs

Labour costs can vary depending on factors such as location, the complexity of the design, and local labour rates. Custom or intricate designs may require more skilled labour, which can increase the overall cost.

4. Site Preparation & Accessibility

If the site where the deck will be built requires significant preparation, such as levelling, removing trees or shrubs, or dealing with challenging terrain, this can add to the cost. The location of the deck and its accessibility can also affect costs. For example, building a deck on a sloped or uneven terrain may require more work and materials.

5. Permits and Codes

Obtaining the necessary permits and ensuring compliance with local building codes may incur additional costs. This can include fees for permits and inspections.

6. Accessories and Finishes

Extras like built-in seating, planters, lighting, railings, and other accessories can add to the cost of the deck. The choice of finishes, stains, or sealants for the deck can also affect the cost. Higher-quality finishes may be more expensive upfront but can provide better protection and longevity.

7. Demolition and Disposal

If there is an existing deck or structure that needs to be removed before building a new one, the cost of demolition and disposal will be a factor.

8. Market Conditions

Economic factors, including the cost of materials and labour in your region, can impact the overall cost. Prices for construction materials can fluctuate based on market conditions.

It’s important to note that the cost of decking can vary widely depending on these factors, as well as other specific considerations unique to your project. We recommend comparing multiple quotes from local decking contractors and considering all aspects of the project before making a decision.

Types of decking materials

One of the hardest decisions to make when you’re planning to create a deck is choosing what material to use.

While there are some basic treated pine products on the market that are fairly inexpensive, if you delve into the world of high-end decking materials, you could wind up spending close to $1,000 per square metre – which could blow out your decking costs considerably.

While the starting point for decking material might be pine, it doesn’t mean this material is inferior. Treated pine is super hardy and can be stained and painted to suit your style and taste.

One the other hand, hardwood timber decking cost is in the middle of the range material-wise. You can choose from a range of species based on your specific choice and what flooring you have throughout the rest of the property.

Finally, the big cheese of the decking material is composite decking, which is made to look like timber but is created in a wide range of colours and styles. The big plus with composite decking is that it doesn’t need the upkeep like timber and treated pine requires and the material is made from a unique mix of timber and plastic – creating a super strong and durable material.

If you don’t know which timber decking to choose, ask your local timber provider about each specific timber and their ability to withstand the elements.

Timber species such as Blackbutt, Merbau, Ironbark, Jarrah and Spotted Gum are great for decks as they are suitable for outdoor use. Each of the materials are super hardy and work to provide a great decking material that will stand the test of time.
